Recent developments in Canada and the United States have brought cannabis/hemp/marijuana back into the news. Clinical studies are underway in both countries to examine marijuana's value for treating symptoms and relieving pain for those who suffer from AIDS, cancer, ALS, MS, epilepsy, arthritis, glaucoma and other serious illnesses. This book is written about the American legal and regulatory systems but has valuable information for anyone whose chronic pain or illness can't be helped by conventinal medicine. 280pp.
